MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Dec. 29, 1914.

Application filed April 10, 1914. Serial No. 831,011.

To all whom it may concern:

Be it known that I, ROY L. VVrinREN, a citizen of the United States, residing at Oxford, in the county of Butler and State of Ohio, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

The invention relates to music leaf turners, and more particularly to the class of spring controlled music leaf turners.

The primary object of the invention is the provision of a music leaf turner wherein a music sheet can be automatically turned without necessitating the handling of the music by the operator of a musical instrument. 7

Another object of the invention is the provision of a music leaf turner wherein the parts thereof are of a novel form and cooperate with each other in a manner for the successive turning of the music to avoid inconvenience to the player of a musical instrument.

A further object of the invention is the provision of a device of this character wherein the arm is reversely moved so as to automatically shift the leaf of music in both directions so that it can be conveniently read for the playing of the same by an operator of a musical instrument.

A still further object of the invention is the provision of a device of this character which is extremely simple in construction, readily and easily applied to a musical instrument or rack, thoroughly reliable and eflicient in its operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

In the drawing: Figure 1 is a front elevation, partly in section, of a music leaf turner constructed in accordance with the invention. Fig. 2 is a horizontal transverse sectional View thereof. Fig. 3 is a vertical longitudinal sectional view of the same. Fig. 4c is a vertical transverse sectional view on the line H of Fig. 1.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the music leaf turner comprises a housing A which may be made from wood, metal, or other suitable material and 1s adapted to be mounted upon a musical instrument or a music rack, the ends of the housing being formed with slotted ears 5 for engagement with any suitable fasteners to secure the same against displacement when supported upon a musical instrument or a music rack.

Journaled centrally in the housing A is a vertical shaft 6 having integrally formed therewith and projecting outwardly at right angles thereto exteriorly of the housing and suitably spaced above its top a music leaf turning arm 7 carrying suitable spring clips or sheet engaging devices 8 for the fastening of the sheet music thereto.

Fixed to the shaft 6 interiorly of the housing A is a pinion 9 meshing with a toothed rack 10 which is mounted in a suitable guideway 11 formed within the housing, and to this toothed rack is pivotally connected one end of a throw rod 12, the opposite end of which is concentrically pivoted to a turning disk 13 fixed to a stud shaft 1 1 ournaled in a suitable bearing 14 mounted within the housing, the disk 13 being rotated in a manner presently described.

Spaced from the stud shaft and within the housing A is a clock spring casing 15 in which is arranged a coiled clock spring 16, one end of which is fixed to the said casing 15 and its opposite end fixed to an arbor 17 carrying a gear 18 which meshes with a companion gear 19 fixed to the stud shaft 14:, the arbor being formed with a key engaging end 20 for the connection of an ordinary clock key 21 therewith so that the spring 16 can be wound as the occasion may require, and during the winding of the said spring the same is checked against unwinding thereof by means of a ratchet mechanism 22, it being apparent that when the rack 10 is released and the spring 16 is unwinding the said rack will be reciprocated, the releasement of the rack being efiected in a manner presently described.

Suitably mounted in the front of the housing A centrally thereof is a latch trigger 22, the inner end of which is formed with a lug 23 arranged in the path of spaced openings 25 formed in the rack 10 so that the lug 23 will engage either of the openings for holding the rack 10 in its shifted position. On operating the trigger 22 the lug 23 is disengaged from the opening 25 in the rack 10, and under the tension of the spring 16 the rack is shifted in a direction for the turning of the arm 7, it being apparent that during a half revolution of the Wheel 13 the arm Will be swung in one direction, and on further rotation of the disk 13 a complete revolution the said arm Will be reversely turned. The trigger 22 looks the rack 10 When moved in one direction or the other to hold the arm 7 against turning movement, and on the release of the rack the arm 7 Will swing for the turning of the sheet music.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

l/Vhat is claimed is A music leaf turner comprising an elongated rectangular shaped housing, a turning shaft journaled centrally Within the housing and extended Without the same in spaced relation to form a music leaf turning arm, means on the arm' for fastening a music leaf thereto, a pinion fixed to said shaft, a toothed rack meshing With said pinion and having openings at intervals in its face opposite the teeth thereof, a guide for the said rack to hold it in meshing engagement with the pinion, a key Wound spring operated motor Withm the housing near one end thereof, connections between said motor and the toothed rack for reciprocating the latter, and a hand operated latch having a lug engageable in any one of the openings in the rack to look the same in shifted position.

In testimony whereof I aflix my signature in presence of tWO Witnesses.
